Question

(x+1/2)(2x−1/2) help.

Answer 1

$\tt \bigg(x + \frac{1}{2} \bigg) \bigg(2x - \frac{1}{2} \bigg) \\ \\ \bf = > {2x}^{2} - \frac{x}{2} + x - \frac{1}{4} \\ \\ = > \bf ({8x}^{2} - 2x + 4x - 1) \frac{1}{4} \\ \\ \bf = > \red{ \big( {8x}^{2} + 2x - 1 \bigg) \frac{1}{4} }$

Answer 2

Answer:

(x+1/2)(2x−1/2)

= x (2x−1/2) + (1/2) (2x−1/2)

= 2x² - x/2 + x - 1/4

= 2x² + x/2 - 1/4
